Comparing the Essential oil Components of Rosa damascena Mill from Three Natural Habitats of the Suburbs of Kashan

Abstract

compounds. The oil and distilled water of Rose are used vastly in medicinal, hygienic-cosmetic and food industries. Due to its adaptation to different climatic conditions, this plant species has spread in many parts of the world and Iran.In this research, chemical composition of threeRosadamascena Millsamples from natural habitat of Kashan were examined. Methods:The aromatic compounds were obtained by SDE method. In this method, 100g of fresh Rosadamascena Millpetals with water was heated for 4 hours, the solvent used in essential oil extraction was hexane. The yields of essential oils from 3 different habitats (Barzok, Kamoo and Qamsar) were calculated. The essential oils were analyzed by GC andGC/MS. Results:The result showed there is no significant difference between essential oil yields at 3 different habitats.SamplesfromBarzokhadhigher percentage of citronellol and sometimes geraniol, but the valuable compound, phenyl ethyl alcohol, was not found in the essential oils or exist in very little citronellol and also geraniol was found in the essential oil, of course in lower amounts. Also, there were some differences between the minor components. Discussion: Considering the essential oil yield and
